The flat is nice, well equipped, and close to Asok BTS. We did not meet Rogier but he was in contact for the check in and check out. He was nicely flexible for check in / out to fit our needs
There is a balcony, but the view is very limited (just to the opposite building).
There is also a small but nice pool, clean and quiet.
Condo's Tuk Tuk is very convenient (and free) to get the BTS, MRT. But on the way back one may hire a motorbike-taxi. Doing that by foot is not a good option since there is not sidewalk all the way.
